I believe most police should be unarmed. If someone attacks them, their job should be to run away and call for backup. Use body cameras to collect evidence to track violent offenders down later. And in order to be armed, an officer should have a 4-year degree that includes a whole lot of training in criminal law.
US troops operating in Kandahar had far more restrictions on use of force than US police do. And people there were actively hunting them. We treat our own citizens worse than foreign enemies, which really needs to change. A big reason for this is that the perceived “enemy” (read: black people) cannot just blend in with the rest of society because of their skin color. That’s pretty fucked up IMO.
